Hi,

I'm using SIPp application http://sipp.sourceforge.net/ to generate a SIP call to open source PBX Asterisk. The application needs of xml configuration file where are specified configuration parameters for SIP channel. In particular i have to set the parameters for SDP protocol which manages the audio/video stream in SIP/RTP call.

I can configure the audio, but not the video...

Command to call the extension (extension) where the IP is IP address of Asterisk


sipp -m 1 -d 36000000 -s extension -sf uac_modified.xml IP configuration file uac_modified.xml
